Types of Pool Heaters

There are several types of pool heaters, including electric, gas, solar and heat pumps. Electric heaters are typically cheaper and require less maintenance, while gas heaters are more cost-effective to run but require a gas line running from the house to the heaters. Heat pumps use the heat from the air to heat your pool, meaning they are more efficient and require less energy. Solar heaters use the sun’s energy to heat your pool, and primarily require little maintenance.


Size and Capacity

The size of the heating unit you choose should depend on the size of your pool and the desired temperature you’d like to maintain. Heaters come in different sizes with different production rates, so you’ll want to consider the size of your pool (in square feet and gallons) when selecting a heater. Most manufacturers will offer guidance to help you choose the appropriate unit size.


Energy Efficiency

When shopping for a pool heater, you’ll want to research the energy efficiency of each model. A higher efficiency rating is important, as it will save you money on your energy bills and reduce your carbon footprint. Electric heaters, gas heaters, and heat pumps all have different levels of energy efficiency, so make sure to check the labels.


Costs and Maintenance

The cost of the heater itself is just one factor to consider when shopping for a pool heater. You also need to think about the running costs, such as gas or electricity, and ongoing maintenance. Gas heaters tend to be more expensive up-front but can be more cost-effective to run, while solar heaters tend to require less maintenance. Think about the type of heater and how much annual maintenance you are willing to do.



When considering features, look for a heater that can be controlled remotely using a digital timer, smart thermostat, or mobile app. It’s also important to check the warranty of each heater you consider, as this can have a big impact on your cost and peace-of-mind.


Customer Reviews

When narrowing down your choices, be sure to read customer reviews to get a better understanding of the pros and cons of each model. Checking out customer reviews can also give you additional insights into user-friendliness, durability, and performance.



If you’re installing the heater yourself, make sure you read the instructions carefully before you begin and follow the tips provided. Even if you’re hiring a professional, ask them whether they have experience working with your type of heater and whether they have any additional tips on installation.



Whichever heater you choose, it’s important to ensure it is compliant with applicable safety standards. Make sure the heater you buy is UL-listed or certified. Check whether the heater requires additional safety devices such as a pressure valve or shut-off switch.

The best-known pool heater brands are Pentair, Hayward, Jandy, and Sta-Rite. Each brand has its own advantages and disadvantages for different types of pools and climates. If you’re uncertain which brand to buy, compare the features and read customer reviews to make an informed decision.
